heck, they can some how use the screen as solar panel to charge the battery.. technology only goes as far as the money you're willing to spend  |
OLED is a good emerging technology, but it's not without it's drawbacks. It's actually possible for an OLED screen to use more energy than a normal LED screens, particularly while displaying white. Unfortunately Li-poly is as good as they come so far. Battery technology doesn't enjoy the same benefits of transistor size reductions and is limited by simple chemical reactions. Until we can leverage nanoparticles or carbon nanotubes in a cost effective way, it's tough to get any more juice. Battery technology grows in leaps as opposed to gradually. As the next 'better' battery components is discovered, capacity/charge rates/energy density leaps ahead. i.e. from Ni-Cd to NiMH to Li-ion to Li-poly.
Even the super high end Tesla Roadster only uses Li-ion batteries and it takes up like half the trunk.
